The present invention relates to a method for a terminal to receive an enhanced physical downlink control channel (EPDCCH) from a based station in a wireless communication system. More particularly, the method includes the steps of: defining a first number of enhanced resource element groups (EREGs) for each resource block for the EPDCCH; monitoring EPDCCH candidates consisting of one or more enhanced control channel elements (ECCEs) in resource blocks so as to receive the EPDCCH, wherein each of the one or more ECCEs consists of a second number of EREGs included in different resource blocks, and the indexes of the resource blocks including the second number of EREGs are determined on the basis of a specific value obtained by dividing the number of resource blocks by the second number.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method according to claim 1 , wherein indexes of the different resource blocks including the second number of EREGs have an interval that is a larger value between 1 and a specific value.
4. The method according to claim 1 , wherein the first number is a fixed value and the second number is a value varying according to a type of a subframe through which the EPDCCH is received.
5. The method according to claim 4 , wherein the second number is 4 or 8 according to a type of a subframe through which the EPDCCH is received.
6. The method according to claim 1 , wherein the defining, by the UE, the first number of EREGs comprises allocating indexes of the EREGs to each of the resource block pairs, wherein the indexes of the EREGs included in each of the resource block pair have values in the range of 0 to 15.
8. The method according to claim 7 , wherein indexes of the resource blocks including the second number of EREGs have an interval that is a larger value between 1 and a specific value.
10. The method according to claim 7 , wherein the first number is a fixed value and the second number is a value varying according to a type of a subframe through which the EPDCCH is transmitted.
11. The method according to claim 10 , wherein the second number is 4 or 8 according to a type of a subframe through which the EPDCCH is transmitted.
12. The method according to claim 7 , wherein the defining, by the base station, the first number of EREGs comprises allocating indexes of the EREGs to each of the resource block pairs, wherein the indexes of the EREGs included in the resource block pair have values in the range of 0 to 15.
13. The method according to claim 1 , wherein indexes of the different resource blocks including the second number of EREGs are determined based on a number of resource block pairs divided by the second number.
14. The method according to claim 7 , wherein indexes of the different resource blocks including the second number of EREGs are determined based on a number of resource block pairs divided by the second number.
